Beschreibung
Zusammenfassung:	The invention relates to the roll seam welding of container frames wherein a first welding procedure is carried out using welding rolls (10, 11) and subsequently the welded frame is fed to a second welding procedure using welding rolls (20, 21). The welding force of the second welding procedure is adjusted in accordance with a welding parameter for welding quality that has been determined during the first welding procedure. In this manner even sheet metals that are difficult to weld can be welded with better welding quality and the welding quality can be improved.
